Choose a learning level that suits you. A Skill Check helps direct you to an appropriate starting point, with options for learners with no prior experience, beginners, intermediate learners, and advanced learners.

Daily Coding Challenges
Build a consistent programming habit with daily lessons, multiple-choice quizzes and coding questions. Practise concepts as you learn and revisit topics that need more attention.

Run Code and Practise in the Playground
Write and run code directly in the app, view execution output, and practise programming concepts without switching between multiple tools. Use the Code Playground to experiment, and the Snippets feature to keep useful examples and your own saved code.

Ask Sky, Your AI Coding Assistant
Need help understanding a programming concept or fixing an error? Sky can help explain coding questions and assist with error screenshots.

Use AI-assisted explanations to understand concepts, explore possible fixes, and learn from mistakes. Always review generated code and explanations before relying on them.

Review Mistakes and Strengthen Weak Topics
Revisit incorrect answers at spaced intervals to reinforce learning. Practise weak areas with AI-assisted exercises where available, rather than simply moving on after a wrong answer.

Track Your Progress
Build a regular learning habit with streaks, XP, achievements and progress tracking. Review your learning progress and earn course-completion certificates where supported.

Coding Accessibility and Flexible Learning
CodeJal includes accessibility options designed to support different learning and interaction needs.

Depending on your settings, you can use:

High-contrast themes, bold text, and adjustable text size

Reading-friendly text spacing and simpler explanations

Spoken explanations and code reading

Screen-reader labels and keyboard or switch navigation

Larger interaction targets and voice-based answer selection

Reduced motion, focus mode and learning without countdown timers

Accessibility presets for different preferences.

You can adjust supported options in Settings > Accessibility.

Sync Your Learning Progress
Sign in with your email or Google account to keep your learning progress synchronised across supported devices.
